please answer following questionHomework Answers
While reading a cell notation its important to remember the Formula 'ABC' (Anode.....Bridge.......Cathode)The first hald is the reaction at anodic half, its an oxidation half constinting of an oxidation reaction while the other reaction is in the cathodic half and its the reduction reaction
Anode: (oxidation half)
2HClO2 + 4H+ + 4e = 2HOCl + 2H2O
Cathode: (reduction half)
4 H+ + 3 MnO4- = 2 H2O + MnO2 + 4e-
